A semi-trailer truck, also known as a semitruck, is the combination of a tractor unit and one or more semi-trailers to carry freight. A semi-trailer attaches to the tractor with a type of hitch called a fifth wheel.
A truck or lorry is a motor vehicle designed to transport cargo, carry specialized payloads, or perform other utilitarian work. Trucks vary greatly in size, power, and configuration, but the vast majority feature body-on-frame construction, with a cabin that is independent of the payload portion of the vehicle. Smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful and may be configured to be mounted with specialized equipment, such as in the case of refuse trucks, fire trucks, concrete mixers, and suction excavators. In American English, a commercial vehicle without a trailer or other articulation is formally a "straight truck" while one designed specifically to pull a trailer is not a truck but a "tractor".
A road train, land train or long combination vehicle (LCV) is a trucking vehicle used to move road freight more efficiently than semi-trailer trucks. It consists of two or more trailers or semi-trailers hauled by a prime mover.
There have been many extremely large explosions, accidental and intentional, caused by modern high explosives, boiling liquid expanding vapour explosions (BLEVEs), older explosives such as gunpowder, volatile petroleum-based fuels such as gasoline, and other chemical reactions. This list contains the largest known examples, sorted by date. An unambiguous ranking in order of severity is not possible; a 1994 study by historian Jay White of 130 large explosions suggested that they need to be ranked by an overall effect of power, quantity, radius, loss of life and property destruction, but concluded that such rankings are difficult to assess.
There have been a number of train accidents on the railway network of Victoria, Australia. Some of these are listed below.
Benjamin Gimbert, an engine driver with the LNER was awarded the George Cross and the Order of Industrial Heroism, as was his fireman James Nightall, whose award was posthumous, for saving an ammunition train from a fire on 2 June 1944 during the Soham rail disaster.
The railways of New South Wales, Australia have had many incidents and accidents since their formation in 1831. There are close to 1000 names associated with rail-related deaths in NSW on the walls of the Australian Railway Monument in Werris Creek. Those killed were all employees of various NSW railways. The details below include deaths of employees and the general public.
Railwayman James William Nightall was posthumously awarded the George Cross and the Order of Industrial Heroism for the gallantry he showed during the Soham rail disaster. Nightall was an LNER Fireman on a fifty-one wagon ammunition train driven by Benjamin Gimbert. When a wagon caught fire, Nightall helped Gimbert uncouple it from the rest of the train in order to allow Gimbert to tow the burning wagon away from the rest of the ammunition wagons on the train. The wagon exploded after being towed a distance 140 yards (130 m), killing Nightall instantly, but preventing a chain reaction in the other wagons. The explosion blew a twenty-foot crater in the track, destroyed Soham railway station, and damaged 600 buildings in the village. Gimbert, who miraculously survived the conflagration, was also awarded the George Cross and Order of Industrial Heroism.
The Soham rail disaster occurred on 2 June 1944, during the Second World War, when a fire developed on the leading wagon of a heavy ammunition train. The wagon contained a quantity of high explosive bombs. The train crew had detached the wagon from the rest of the train and were drawing it away when the cargo exploded. The fireman of the train and the signalman at Soham signalbox were killed and several other people injured. The driver, Benjamin Gimbert, and fireman, James Nightall, were both awarded the George Cross for preventing further damage which would have occurred if the rest of the train had exploded.
